does anybody know how to find out the number of
days elapsed between 2 dates
e.g.
days elapsed between 020212 and 020110 (YYMMDD format)
Thanking you in advance.

Hi
I'm looking for a .ksh script/function that will calculate ONLY the number of days between two distinct dates. Further convert the number of days to weeks and display. I need this to be part of another larger script that checks the password expiry on several servers and notifies the... (1 Reply)
Hello,
I would like to find out the number of days between two dates of the format yyyy-mm-dd.
Any help on this is highly appreciated.

I am familiar with using the 'date' command to get the current date but I have a situation where I need to get the previous day's date as well as the date two days prior. Theoretically I could use 'expr' to compute these values but I need it to work in instances where the previous month's dates... (2 Replies)
Hi
I need one single command to get number of days between
two given dates.datecalc is not working.
ex.
fromdate:01.04.2010
todate :24.04.2010
i should get the out put as 23

I have two times in the format of YYMMDD. Does anyone know an easy way in ksh for me to display how many days are between the two dates?
Example1:
X=101202
Y=101205
There are 3 days between X & Y
Example2:
X=101202
Y=111202
There are 365 days between X & Y
Example3:
X=101205... (3 Replies)
I extract dates from the log file and need to calculate days between two dates. My dates are in yyyyMmmdd format. Example:
$d1=2011 Oct 21
$d2=2012 Feb 20
I need to calculate the number of days between $d2 and $d1. This is on Solaris.
Any ideas?
Thanks,

slarrj
slarrj.f(3) LAPACK slarrj.f(3)NAME
slarrj.f -
SYNOPSIS
Functions/Subroutines
subroutine slarrj (N, D, E2, IFIRST, ILAST, RTOL, OFFSET, W, WERR, WORK, IWORK, PIVMIN, SPDIAM, INFO)
SLARRJ performs refinement of the initial estimates of the eigenvalues of the matrix T.
Function/Subroutine Documentation
subroutine slarrj (integerN, real, dimension( * )D, real, dimension( * )E2, integerIFIRST, integerILAST, realRTOL, integerOFFSET, real,
dimension( * )W, real, dimension( * )WERR, real, dimension( * )WORK, integer, dimension( * )IWORK, realPIVMIN, realSPDIAM, integerINFO)
SLARRJ performs refinement of the initial estimates of the eigenvalues of the matrix T.
Purpose:
Given the initial eigenvalue approximations of T, SLARRJ
does bisection to refine the eigenvalues of T,
W( IFIRST-OFFSET ) through W( ILAST-OFFSET ), to more accuracy. Initial
guesses for these eigenvalues are input in W, the corresponding estimate
of the error in these guesses in WERR. During bisection, intervals
[left, right] are maintained by storing their mid-points and
semi-widths in the arrays W and WERR respectively.
Parameters:
N
N is INTEGER
The order of the matrix.
D
D is REAL array, dimension (N)
The N diagonal elements of T.
E2
E2 is REAL array, dimension (N-1)
The Squares of the (N-1) subdiagonal elements of T.
IFIRST
IFIRST is INTEGER
The index of the first eigenvalue to be computed.
ILAST
ILAST is INTEGER
The index of the last eigenvalue to be computed.
RTOL
RTOL is REAL
Tolerance for the convergence of the bisection intervals.
An interval [LEFT,RIGHT] has converged if
RIGHT-LEFT.LT.RTOL*MAX(|LEFT|,|RIGHT|).
OFFSET
OFFSET is INTEGER
Offset for the arrays W and WERR, i.e., the IFIRST-OFFSET
through ILAST-OFFSET elements of these arrays are to be used.
W
W is REAL array, dimension (N)
On input, W( IFIRST-OFFSET ) through W( ILAST-OFFSET ) are
estimates of the eigenvalues of L D L^T indexed IFIRST through
ILAST.
On output, these estimates are refined.
WERR
WERR is REAL array, dimension (N)
On input, WERR( IFIRST-OFFSET ) through WERR( ILAST-OFFSET ) are
the errors in the estimates of the corresponding elements in W.
On output, these errors are refined.
WORK
WORK is REAL array, dimension (2*N)
Workspace.
IWORK
IWORK is INTEGER array, dimension (2*N)
Workspace.
PIVMIN
PIVMIN is REAL
The minimum pivot in the Sturm sequence for T.
SPDIAM
SPDIAM is REAL
The spectral diameter of T.
INFO
INFO is INTEGER
Error flag.
